Application filed June 8,

To all whom it may concern: i

Be it known that l, LELAND S. Rosanna, a citizen of the United States, and resident of the city and county of San Francisco, State of California, have invented new. and useful Improvements in Coaling Barges, of which the following is a specification.

My invention has for its object mechanism whereby a barge or the like carrying a load of coal'may be quickly and efficiently unloaded into a steamer, wharf or the like and is primarily for effecting the rapid and economical coaling of ships either while lying in the stream or in confined quarters along side of a wharf.

Reference is herein made to my copending applications Serial 331,085, filed Oct. 16, 1919; 344,259, filed Dec. 11, 1919, and fierial No. 475,910, filed tlune S, 1921,wherein are set forth other devices and inventions in this same art.

By referring to the accompanying drawings my invention will be made clear.

Fig. 1 is a plan view of a barge equipped with coaling apparatus of my invention.

Fig. 2 is side elevation of Fig. 1.

Fig. 3 is cross section of Fig. 2 on the line III-III thereof.

Fig. 4 is a detail of track supporting means as mounted on the deck trusses and is an enlarged view of a portion of Fig. 3.

Throughout the figures similar numerals refer to identical parts.

The hull of the barge is shown by the numeral 1 within which is bunker space as 2, 3, 4, 5, 6. The sides of the barge being supported by the deck trusses 7, 8, 9, which in the barge chosen for illustration are ar ranged transversely of the bunker space. Longitudinally over the bunkers and supported on the said trusses I mount the track supports 1,0. 11. carrying thereon suitable tracks 12, 13. respectively. The gantry crane mounted upon rollers '14. 15. and carried on A frames 16, 1.7. the bridge member 13 and is adapted to travel on the aforesaid tracks '12. 13. from end to end of thebarge. On the bridge 18 is mounted the trolley 19 from which is suspended the grab bucket 20 by suitable raising and lowering. and opening and closing cables. The hull of the barge is provided with a floor 21 for the bunkers and sloping sides 22, 23, at an angle with the aforesaidfloorin excess of the an lgle of repose of coal or other load that the barge is adapted to carry, so that any coal 1921. serial at. 475,909.

within the bunkers will have a constant tendency to travel towards the floor 21. The bridge 18, trolley 19 and bucket 20 and the trolley tracks 24 areso proportioned that the grab bucket has. a lateral range of travel toreach the load on the floor 21, 'and the crane is adapted to travel over a range such that the bucket 20 may reach any portion of the bunkers 2, 3, 4, 5, 6. At 25 is a hopper preferably positioned substantially in the center of the barge and supported from the deck trusses as by the angle piece 46 and truss 47 and from which a chute 26 is adapted to deliver a load that may be emptled into the hopper 25 and which passes through the said chute and into the skip 27. The skip 27 is adapted'to travel in the vertical ways 28, 29, by the lifting rope 30 carried over the pulleys 31. 31, and actuated by the engine and winding drum at 33. At 34 is a discharge chute which is made adjustable in suitable ways similar to 29, 30, and parallel thereto and it may be raised and lowered by rope 35 actuated by the drum and engine at 36 so that the said hopper 34 may be moved into any desired position vertically with respect to the hull 1, to discharge the load, as indicated by the arrow 37 into the hull of the ship being coaled or on the wharf or any other desired location and at any required elevation. The skip 27 and the discharge chute 34 herein set forth are shown in greater detail in my copending applications and especially in Serial No. 331,085, filed Oct. 16. 1919, together with the means and manner of tripping the skip to automatically discharge into the discharge chute and also the means and manner of weighing the unit loads. lit will also be understood that the bucket 20 and its operating cables may be actuated electrically or by other power means in well known ways. details of which form. no part of my present invention. The operation is as follows:

A. load. as of coal. contained in the bunk- 4. 5. 6. is unloaded through the discharge hopper 34 as indicated by the arrow 37 by being raised in the bucket 20 from any position over the said bunkers when the gantry crane then moved to a position so that the bucket will empty into the hopper 25 (see Fig. 3) from which the unit load will pass through the chute 26into the skip 27 and then be raised until the skip dumps into the discharge chute 34 when the load travels by gravity in the direction of the ers arrow 37. At 40 is shown the steam boiler for operating the engines and drums 33, 3G, and such other power means as may be required.

I claim:

1.. In combination with a barge having bunker space a pair of tracks disposed lon gitudina-lly of the barge and over the said bunker space, a gallows frame positioned amidships and to" one side of said tracks and having ways therein, a skip adapted to travel to any vertical position on said ways and in said frame and hoisting means therefor, a discharge hopper and chute movably mounted in. said frame and adapted to receive a load from said skip and transfer the same by gravity clear of said barge, a bridge movable on said tracks, a grab bucket suspended from a trolley, said trolley movable on the bridge and transversely of the barge, means for operating the bucket and means for operating-the bridge and a receiving hopper into which the bucket is adapted to deliver its load and a chute from said receiving hopper adapted to transfer said load to said ski 2. In combination with a barge, apparatus as set forth in claim 1 wherein the receiving hopper is located between the tracks and the chute therefrom to said skip passes uu der one of the said tracks.

In combination with a barge, apparatus as set forth in claim 1 wherein the receiving hopper is located between the tracks and the chute therefrom to said skip passes under I one of the said tracks, andv wherein the said tracks are supported from transverse beams bridging said bunker space 4:. A barge and apparatus as set forth in claim 1. wherein said bunker space is provided with side walls sloping toward the center whereby the load in the bunkers is caused to travel within the working ran go of the grab bucket as the bunker space is unloaded.

In combination with a-barge,apparatus as set forth. in claim t wherein the rereiviun hopper is located between the tracks and the chute therefrom to said skip passes under one of the tracks.

6. In combination with a barge, apparatus as set forth in claim 4: wherein the receiving hopper is located between the tracks and the chute therefrom to said skip passes under one of the tracks and wherein the tracks are supported from transverse beams bridging said bunker space.
